RFR [11]: 8207235: ManagementFactory.getPlatformMXBeans(BufferPoolMXBean.class) throws NPE

[Claes Redestad]

Hi,

the JavaNioAccess shared secret is being created by java.nio.Bits, but 
since it's non-public SharedSecrets has been using an indirection to 
ensure it gets loaded when needed. JDK-8201494 unintentionally broke 
this indirect dependency.

One solution is to move the creation of the shared secret class to a 
public class in java.nio, allowing for a direct dependency.
